A box of staples contains 6 x 103 staples and weighs 12 oz. How much does one staple
weigh? Write your answer in scientific notation. Round your answer to the nearest tenth, if
necessary.
Answer:
2 * 10^-3 oz
Step-by-step explanation:
Given that:
Number of staples per box = 6 * 10^3
Weight of staple box = 12 oz
Weight per staple = (weight of staple box / number of staples per box)
Weight per staple = 12 / 6 * 10^3
Weight per staple = 12 / 6 * 1000
= 12 / 6000
= 0.002 oz
= 2 * 10^-3 oz

Andre ran 2 kilometers in 15 minutes and Jada ran 3 kilometers in 20 minutes. Both ran at a constant speed. Did they run the same rate? Explain or show your reasoning.
You might use:
-ratio tables
-double number lines
-unit rates
-Equivalent ratios
yeah
Answer:
no, Andre ran at a sperm of 8km/hr while jada ran at 9km/hr you can find that by Andre going 2km in 15 minutes which turns to hours by multiplying by 4/4 to get 8/60 which 60 minutes is 1 hour then jada multiply by 3/3 which would be 9/60
Create an equation with one solution of x = −5.
9x − (x − 3) = 2x − (__ + x)
7.4 #7
Answer:
9x-(x-3) = 2x - (-5 + x)
Step-by-step explanation:
Let's say blank is the variable a.
9x-(x-3) = 2x - (a + x)
Simplify the equation:
9x-(x-3) = 2x - ( a + x)
9x - x + 3 = 2x - a - x
8x + 3 = x - a
7x + 3 = -a
a = -7x - 3
Plug in -5 for x:
a = -7*-5 - 3 = 35 - 3 = 32
a = 32 so the equation with one solution of x = -5 would
9x-(x-3) = 2x - (-5 + x)

There were 52 riders on a bus. The next bus had 25% more riders. How many riders were on the next bus?
Answer:
65 riders
Step-by-step explanation:
52 times 0.25 = 13 (25% of 52)
52 + 13 = 65
Answer:
There were 65 riders on the next bus.
Step-by-step explanation:
To solve this you have to know what 25% of 52 is, and since 25% of 52 is 13, you have to add 52 and 13 so you get 65 as your result.

cross product
5*40=1*x
200=x
Answer:
200 eggs
Step-by-step explanation:
First I divided 35 by 7 and got the answer 5. This means that each chicken will lay 5 eggs. 40 x 5 = 200. So 40 chickens will lay 200 eggs.

please solve this class 10 function
if f={(x,y):3y-2x=6} find f-¹(x)
Answer:
f −1 (x)= x/2+3
Step-by-step explanation:
Here take y=f(x)
Then y=2x−6
⇒2x=y+6
⇒x= y/2 +3
Now switch x and y in the resulting equation. The resulting function of x is the inverse.
⇒y= x/2 +3
Thus the inverse function is f −1 (x)= x/2+3

Find the solution to the system of equations. You can use the interactive graph below to find the solution. 8x + 4y = 24
-7x + 7y = 28
x=
y=
Answer:
X=11y+4 y= -1/11x + 4/11
Step-by-step explanation:
Let's solve for x.
8x+4y+24−7x+7y=28
Step 1: Add -24 to both sides.
x+11y+24+−24=28+−24
x+11y=4
Step 2: Add -11y to both sides.
x+11y+−11y=4+−11y
________________________________
answer: x=−11y+4
_______________________________
Let's solve for y.
8x+4y+24−7x+7y=28
Step 1: Add -24 to both sides.
x+11y+24+−24=28+−24
x+11y=4
Step 2: Add -x to both sides.
x+11y+−x=4+−x
11y=−x+4
Step 3: Divide both sides by 11.
11
11y/11 = - x+4/11
y=-1/11x +4/1

Which ratio is equivalent to y : x ?
A. 3:3
B. 4:3
C: 7:3
D: 3:7
Answer:
B. 4:3

Note: I use the '&' mark to symbolize mixed fractions, since it's easy to mistake the whole number for part of the numerator. Don't do this for assignments, as it's not proper.
1 & 1/3 = 4/3
Thus, the answer is B. 4:3.

Answer:
A. 0, - 9
Step-by-step explanation:
Given
x² + 9x = 0
x (x + 9 ) = 0
Either
x = 0
or,
x + 9 = 0
x = - 9
Hope it will help :)
The values of x that satisfy the equation x² + 9x = 0 are x = 0 and x = -9.
Option A is the correct answer.
What is an equation?An equation contains one or more terms with variables connected by an equal sign.
Example:
2x + 4y = 9 is an equation.
2x = 8 is an equation.
We have,
x² + 9x = 0
To solve for x, we can factor the expression:
x(x + 9) = 0
According to the zero product property, this equation is satisfied if either x = 0 or x + 9 = 0.
We have two solutions:
x = 0 or x = -9
Therefore,
The values of x that satisfy the equation x² + 9x = 0 are x = 0 and x = -9.

The price of a cup of coffee has dropped to $2.50 today. Yesterday's price was $2.75. Find the percentage decrease. Round your answer to the nearest tenth of
a percent.
Answer:
9.1%
Step-by-step explanation:
The price of a coffee has dropped to $2.50
Yesterday the price was $2.75
Therefore the percentage decrease can be calculated as follows
= 2.50 - 2.75/2.75 × 100
= -0.25/2.75 ×100
= 0.09090 × 100
= 9.1%
Hence the percentage decrease is 9.1%
